All tunes increase low and midrange power and that simply overwhelms the tires as the torque surge is so strong. A tuned M2C will likely be slower in the 1/4 mile and one the road course because it will be roasting the tires and hard to handle.

BM3 allows tunes to reduce torque in whatever gear you want so you can have less traction issues. SO you could reduce target boost by 20% across gears 1-3 for example but have the full power of the tune in higher gears.
